How to Secure Data in AI: Essential Guide to PII Masking in LangChain

[@shekharkalshetti4221]

What if the PII isn't of a known format? For example if we're dealing with a patient report we need to mask records accordingly i.e if BP is higher than 120mmHg it should say high BP instead of the actual metrics.

This is definitely complicated. I know people are using AI to self evaluate to mask PHI data. So you could potentially use a fine tuned model to act as a guard rail and detect it. It's also a way to potentially detect and flag/label prompt injection for security purposes.
